Can't say anything about Nix's ability but if he's not a potential stud I'd prefer to bring back Jolly or Pickett for this year and see how guys like Boyd, Worthy and Guion work in situational roles backing up along the D-Line then see if there's anything to worry about next offseason - especially if a big guy's being flagged for questionable work-ethic. Maybe it's undeserved but those guys can go downhill quickly if they even show up at all.
